Monitoring Distributed Real-Time Systems: A Survey and Future Directions
Alwyn E. Goodloe, Lee Pike · 2010
Runtime monitors have been proposed as a means to increase the reliability of safety-critical systems. In particular, this report addresses runtime monitors for distributed hard real-time systems, such as faulttolerant data buses and control systems for avionics and spacecraft are explored. This class of systems has had little attention from the monitoring community. The need for monitors is shown by discussing examples of avionic systems failure. We survey related work in the field of runtime monitoring. Several potential monitoring architectures for distributed real-time systems are presented along with a discussion of
